Question

When lead ($Pb$) is reacted with the hydrochloric acid a gas is evolved. Name the gas.

• A. Hydrogen gas
• B. Chlorine gas
• C. Both hydrogen gas and chlorine gas
• D. None of them

Answer 1

The correct option is A Hydrogen gas

Lead ($Pb$) reacts with hydrochloric acid ($HCl$) to form lead chloride ($PbC{l}_2$) and bubbles of hydrogen ($H_2$) gas. The equation can be written as:
$Pb\left(s\right)+2HCl\left(aq\right)\to PbC{l}_2\left(aq\right)+H_2\left(g\right)$
